. To all whom it may tion of the same- Fig. 7 is adetail view Be it knpwn that we, VI'VIAN T. More and HUBERT E. More, subjects of the King of' Great Britain, residing at Cradock, ape Colony, South Africa, have invented new' and useful Improvements. in Liquid-Dis. pensing Devices, of which the following is: a s ecification.

his invention relates to a liquid dispensing device for attachment to bottles, where-f by a desired measured quantity of the liquid may be dispensed, the object of the inven-1 tion being to provide a device of this character which is simple of construction, adapted for use in connection with bottles of; difi'erent sizes, susceptible of being readily; and conveniently cleaned, and operative to; automatically cut off the flow of liquid when; the proper amount is measured out, thus, securing absolute accuracy in the measuring; operation. i The invention consists'of the features of; construction, combination and arrangement of parts, hereinafter fully described and; claimed, reference being had to the accom panying drawings, in which Figure 1' is a perspective view ofa bottle' embodying the invention and inverted tomeasure a prescribed quantity of liquid for discharge, a portion of the air tube beingv omitted. Fig. 2 is a central vertical section of the distributer detached. Fig. 3 is a similar view of a modified form thereof, a portion of the air tube in this view also being omitted. Fig. 4 is a view showing the bottle tilted for discharge of the measured quantity of liquid, and lllustrating a modified form of air inlet tube. Fi 5 is a perspective view of another modi ed constructlon of distributer. Fig. 6 is a vertical secshowing a still further modification. Fig. 8 is a view similar to Figs. 2 and 3, showing a form of distributer in which an air inlet tube is dispensed with.

Referring to the drawings, 1 designates a measuring vessel of cylindrlcal or other suitable form, said vesselbeing provided at one side near its base with an air inlet aperture 2 and at the opposite sideof its base below d[ilan'e ofsaid aperture with a =down-' war y projecting discharge nozzle 3. The bottom of the chamber is provided with a flaring or conical nipple 4 to receive and hold the upper enlarged end of a correspondin'gly shaped stopper 5. This stopper bottles,

2 in any terialan'd is adapted to fit within the. neck 6 of the bottle '7 tightly to attach the device thereto and form an effective seal against ,leakage of the liquid contained in the bottle.

The stopper 5 is provided with a vertical passage which is lined by a metallic guide tube 8 in which-is fitted to slide a conducting tube 9, hereinafter called the admission tube, for discharging the liquid from the bottle, said tube being adjustably mounted in the stopperso that its outer end 10 may be projected to a greater or less extent into the vessel 1. The lower end of the tube is .provided with suitable graduations 11 adapted to be adjusted into registry with 5 is composed of corkor other suitable mathe base of the stopper so as to accurately position the tube for measuring out different quantities of the liquid. When the device is designed as an attachment for measuring the graduations may" be arranged formeasurin out any amount from'ateaspoon 'to a tilespoon, more or'less, but in the adaptation of the invention to large receptacles-the graduations' may be arranged suitable manner to measure out larger quantities.

Extending longitudinally through the admission tube 9 is an air outlet tube 12, which opens laterally at its outer end 13 through the upper end of the admission tube at the side opposite and above the air inlet opening 2 and below the tip10 of said admission tube, the purpose of said tube 12 being to allow air to enter the bottle to take the place of the discharging liquid. Where the llquid .is thin or the mouth of thebottle is sufliciently wide to permit air to enter while the liquid is flowing out, the tube 12 may be .omltted, or with narrow-necked bottles extend but a short distance into the body of the bottle. If, however, the contents of the bottle are of a thick or syrupy character,

the tube 12 is made of a length to extend downward to the bottom of the bottle and is provided at its lower end with an inlet 14 inclos'ing a check valve 15, which seats upwfardly when the bottle is upright to prevent the liquid from entering the tube and is adapted to be. unseated by the pressure of the air when the bottle is inverted to allow the air 'to flow into the bottom portion of the bottle left vacant by the liquid. Figs. 1, 2 and 3 disclose the use of a ong valved air tube, Fig. the use of a short air tube and Fig. 8 a co struction omitting the air tube, as above described. The upper end of the vessel 1 is provided with a flaring nipple 16 adapted to receive and to be closed by a plug or stopper 17. When the device is used constantly it may be reversed after each use and the stopper inserted into the mouth of the bottle to close the same. At all other times the bottle is closed by its original stopper. The stoppers 5 and 17 are removably fitted so as to be easily renewed from time-to-time.

In the operation of the device thus far described, it will be understood that the tube 9 is adjusted to bring the desired raduation into registry with the base 0 the stopper 5 for positioning said tube to measure out the required amount, which operation may be conveniently accomplished by the provision of a flange 'or bead 18 upon the lower'end of the tube serving as a finger grip. The end 10 of the tube will thus be projected to a greater or less extent into the vessel 1 to serve as a gage regulating the measuring distance between said end 10 and the upper end of the cup. The device is then applied to the bottle and the latter inverted, as shown in Fig. 1, causing-liquid to flow from the bottle through the tube 9 into the inverted top of the vessel, which forms a measuring cup, air simultaneously enter ing the bottle through the tube 12 to take the place of the discharging liquid. The liquid will continue to flow from the bottle into thevessel until the outer end or cup portion thereof is filled up to the level of the mouth; 13 of the air tube projecting through the admission tube, which tubewill then be automatically sealed, thus cutting off the flow of% liquid at the exact. moment the required amount of liquid is measured out. By then tilting the bottle to the posit-ion shown in Fig. 4, in which the nozzle 3 is projected downwardly, the liquid will discharge through said nozzle into'any suitable receptacle held below it, while air enters to take its place through the aperture 2. The device may then be removed and cleansed and stored away for future use, and the bottle closed by its closing stopper. In the absence of an air tube, as shown in Fig. 8, the cup will be filled to the level of'the end of the discharge tube, which will thus be sealed. When it is desired to employ the dispensing device solely for the purpose of measuring out a fixed quantity of liquid at all times, the tube 9 may be fixed within the stopper portion 5 to project the required distance into the vessel 1, as'shown in Fig. 3,

inwhich event the graduations 11, may,

of course, be dispensed with.

In the modified form. of our invention shown in Figs. 5 and 6 the measuring ves= sel 1 comprlses two telescopic sections 19 and 20, the top section 20 being movable within the bottom section 19, and the admission tube 9" is rigidly mounted in the. stopper to maintain a fixed posit-ion, its upper or outlet end 10 being contracted, as shown. The two sections 19 and 20 have a screwthreaded engagement to permit adjustment of the section 20 in and out, the section 19 .being provided for this purpose with a. continuous spiral groove or thread 21, while the section 20 is provided with a coacting spiral thread formed of separated ortions 22, the groove and separated threa s being loosely engaged so that said grooves wil1 form said channels for the free passage of air into the device, the threaded enga ement allowing the sect-ion 20 to be adjuste to regulate and register the distance between its top or outer end and the end 10 of the admission tube, to regulate the effective depth of the'measuring cup and consequently the amount of liquid which will be received therein up to the time the end of the admission tube is sealed and the How cut off, as hereinbefore described. The top of the section 20 carries a conical cap 23 adapted when said section is adjusted inwardly to its fullest extent, to telescope over and close the end 10 of the tube, by which the discharge of liquid will.

be prevented. This form of dispensing device may be used as a permanent attachment to the bottle, if desired, the cap 23 preventing evaporation of the contents. In the modified form shown in Fig. 7, the top of the section 20 carries a suitable inwardly projecting stopper 24 to close the end of the admission tube in a similar manner, and, as also shown, may be provided with a nipple or socket 25 to receive the bottle stopper 17, whereby the dispensing device may be inverted and the stopper 17 'fitted within the bottle neck to tightly, close the same.

From the foregoing description, taken in connection with the drawings, the constru'ction and mode of use of our liquid dispensing device will be readily understood, and it will be seen that a device of this kind is provided which embodies the several advantages hereinbefore set forth and provides a device which may be readily and conveniently cleaned after use and which insures accuracy in measuring out a desired quantity of liquid.

By the use of the words upwardly, upper, lower and the like, in the claims, it will be understood that we mean the arrangement of the parts referred to with respect to the bottle or passage when the latter is disposed in a normal upright position.
